How can I turn off 14 day PRO free trial?

I want to use just my own API key. I want to prevent ANY code to be sent to cursor services. There are some Cursor features in PRO that are used automatically, even if i enable my own API key. I.e. Cursor Tab, but probably also some other functionalities. I know I can disable Cursor tab manually. But I would prefer one switch that would disable all features that are sending code to cursor services.
